METALBASE FOR 'rnuen'aronn'sfi Application filed January et, 1927.SerialNo. 158 ,96O ,1.

: This invention relates to protecting-and supportingfbases or repairelements for-poles carrying ele'ctric transm ssion W1res. f '7 of. thepole.

Telephone, telegraph, and electric trans mission wires are usuallycarried .on' lround poles set in holes in the ground. Thesepoles aresubject to rapid decaywbecauseof their .be'ingkeptinasemi-inoistycondition by their contact-:with the soil. vThis decayoccurs from lito 2 feet below the groundline,-the pole both above andbelow this zone of decay .abeing-reasonably durable, andrepairsareusually made either by building a reinforced concrete base around: thepole to span the decayed. portion or more commonly by wiring or boltingthe pole to a timber post or- .stub setdeep intothe ground at thebaseneediof repairs or replacement caused by the decay at the base of thepoles and which will also furnish a cheap and substantially permanentbase for new I poles. Y Y Another object of the invention is theprovision of a device] for not only preventing Y decay ofthe basesof newtelephoneand telegraph poles by maintaining the timber} part of thepoles above ground but for protecting both" newand old poles againstdestruction from grass'andbrush fires by a metal covering of sightlyappearance which extends above the Y ground, a suiiicient distance forthep rpo Y Q 1 A further objeet of the invention isthe provision ofsupporting and, protecting metal coverings for electric transmissionline poles vwhich may be readily'driven into position thus eliminatingthecases of the usual unsightly and expensive concrete bases em- Yployed in supporting and protecting. the

Y K decayed bases of poles.

1 The invention consists of a cylindrical metalsleeve which is fittedtightly around the sound part of the, pole abovethe ground and extended;a sufiicient distance into the ground to give proper; support. In thecase Y the sleeve also fits tightly aroundthe sound part of the-poleandbelow Y thedecayed part'.' In the caseot a. new. pole, the ,sleeve isfittedtightly aroundthe basecf "the .pole which is keptjabovethe jground line, and the cylindrical, sleeve 7 is extended the properdistance into the ground lLOQgiVBjI the necessarysupport; I v c I Thesleeve COHSISlJS of Y a metal tube or eylinder of c rcular contour maden' tvvo or Y more sections lO and 1 1 bysplitting on; a plane'passingthrough its longitudinal'cention of a cylinder of approximatelyjthe samediameter as the pole it is: intended to fit and The parts of the sleevemay either be made in halves with two forming a complete cylinderorthey-may. be

The edges 13 of-the rolled sheets are connected bya locking deviceconsisting of a,T

as the sleeve with 2 L sections or lock bars of the same length. Eachwing 16 of the top of the T is formed to fit the inside of one of thecorrugations 12 of the sleeve, and one leg 17 of each 'L is formed tothe outside of one of these corrugations, while the other leg 18 of theL is-made to fit the straight leg the parts of the sleeves to the lockframe and 'erly' fitted, the corrugations stretched jand' sol'ne'whatbedded due to the foi' eingofthe tightly fitting sleeve through theframe, to each other, but permitting longitudinal motion of the sectionswith respect to the lock joint or each other.

In applying the device to an old pole already in'theground, two or moresections are selected of such size that when secured together by thelock joint, the completed sleeve wilhfit'tightly around the pole. Thesections are held against the pole with the lock frames place engagingwith the corruga-' tions of the sleeve. The lock bars'are then insertedin thetop of the lock frame-as -shown in Fig. 3. They are then drivendownas shown in Fig. 4,1'With their ends flush with the top and bottomof the sleeve. Thesleeve' is then either driven or "j acked"d'ownfaround the-base of the-pole 20 to the proper 'posit'ion asshownin Fig. 5, with the tops 21 of the sections 10 and 11' projectingabove the ground.

"In this position, ifthe sleeve has been propwill be slightly in' the"pole down over theincr'easing diameter of "the 'tapered "pole. Thiswill provide an elastic 'eleme'nt to 'take'c'are of the expansion andco'ntraction'of the sleeve from. temperature andof' the pole frommoisture. p

' In using the device in connection with new poles, one orinoresectionsof the sleeve, 'formingftogether not'more than half a com ple'te sleeve,are driven a short distance into the'ground, The pole is then erectedand held against'the"'driven sections of the sleeve. "Theremaining'sections of the sleeve are then placed around'the pole andsecured to the driveirpartby the lock joints. The newly placed sectionsare then driven to {the same position as the first driven sections, and

the operation [is completed by successive alternate dr'ivingof thesections of the sleeve "to th'eiriprop'er'depth.

The substitution of the driving of metal sections-forthe ordinaryprocess of digging deep holes and refilling them is a great savround. 7The'm'etal'base is neat and attractive in appearance as compared withthe repairing of old poles by any other method-and especially by theusual process of stubbing.

The cost of the metal base in place is less than the cost of the extralength of a new pole without the metal base and the labor of digging andsetting, and is less than the cost of the labor and material forconcrete bases or for stubbing on old poles.

The metal base can be protected bygalthe sleeve being firmlyjoinedtogether in'ia circumferential direction but having free movementparallel to the axis of the cylinder along a joint made of a combinationof'a T shaped bar with two L shaped barswhich together form the joint,thetop ofthe-T being corrugated tofit interior-ly with the corrugationsof the sleeves, the lego f the'T passing between the parallel edgesofthesections'of the sleeveand having a cross at'its exterior and bearingagainst the exterior ends of the legs of the two L barsyone'leg of eachof which is corrugated to*fit"the exterior corrugation of the sleeve,an'dthe locking being effected by the clamping offlthe' corrugations ofthe sleeves between" the conforming corrugations of the 1nter1orT"barsand the exterior l. bars.
